Problems solved by technology

At present, the most common engine air filter element is resin-impregnated pleated filter paper, which cannot be reused and has a short service life, while other filter element materials such as microporous filter paper materials, non-woven fabric materials, and composite filter materials are inferior in performance and cost. It is difficult to achieve the ideal level, therefore, how to get a better performance of the air filter element is a technical problem to be solved

Abstract

The invention discloses a preparation method of a wood fiber air filter core, and relates to the technical field of filter cores. The preparation method of the wood fiber air filter core comprises thefollowing steps: (1) treating a fraxinus mandshurica fiber raw material by adopting a treating fluid; (2) extracting the treated slurry; (3) grinding by adopting flaky sericite. The wood fiber air filter core prepared by the invention has good filtering efficiency and long service life.

Description

technical field [0001] The invention belongs to the technical field of filter elements, and in particular relates to a method for preparing a wood fiber air filter element. Background technique [0002] As an important part of the air intake system of the automobile engine, the quality of the automobile air filter directly affects the reliability and service life of the engine. At present, the most common engine air filter element is resin-impregnated pleated filter paper, which cannot be reused and has a short service life, while other filter element materials such as microporous filter paper materials, non-woven fabric materials, and composite filter materials are inferior in performance and cost. It is difficult to reach the ideal level, therefore, how to obtain a better performance of the air filter element is a technical problem to be solved. Contents of the invention [0003] The object of the present invention is to provide a wood fiber air filter element for the e...
